First which form factor you have, look at those pictures and identify yours



If it is MT, then almost everything will fit, if it is other 3 form factors - your situation is more difficult.
Regarding power supply, 600 watt is more than enough even for GTX 660 card...

I take my words back. This card cannot fit in GX620, only a few good ones can fit, 7770 and GTX 650 (non TI) can fit. I am looking for my previous post about it

THIS POST APPLICABLE TO MT (MINI TOWER) FORM FACTOR ONLY.

Unfortunately no card that is more than 7.5 inches long or 2 slots wide will PHYSICALLY FIT inside the case - it was found that only single bracket video card can fit due to BTX MOBO, where card internals facing upward towards PC internals, not ATX, where dual card design is blocking another PCI slot by facing downward.
If you prefer the card with beefier fan, then the length of the card must not exceed 7.5 inches, otherwise only "skinny" single bracket, single slot cards can physically fit.

Pictures below will prove my point.

View shows no room for dual bracket



Single bracket only, or you have to cut dual bracket in half



Here you can clearly see only single place for the bracket



Visual explanation



7.5 inches explained, also shown "obstacles"



This is the picture of actual "skinny" single slot video card (not sure which model)- perfect, "glove" fit.



So, I found 2 GDDR5 7750 cards and one DDR3 4GB (GDDR5 is better than GDDR3, even if GDD3 offers 2 GB RAM or more), which confirmed in reviews to fit Optiplex gx620, 745 and 755 cases (the difference between those models are different processors).

Skinny, flimsier in terms of construction, completely single slot XFX 7750 http://www.amazon.com/XFX-DisplayPort-PCI-Express-FX775...

A bit beefier cooler, not as skinny, more durable in construction PowerColor AX7750 http://www.amazon.com/PowerColor-AX7750-1GBD5-DH-Video-...

If you need Video card for working with high resolutions, BUT NOT FOR GAMING, PowerColor AX7750 4GBK3-H Radeon HD 7750 4GB is DDR3 card with huge 4GB memory, but is is not as fast as DDR5 and loosing in games http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Here is review of this card http://news.softpedia.com/news/PowerColor-Launches-Sing... so this one is not for gamers!

I cannot say which one of those 2 DDR5 is better, both are good and got less bad reviews related to structural build.
I saw recent recommendation regarding drivers "Changing to the just-released AMD catalyst 13.2 BETA driver improved performance noticeably in just about every game" posted 03/05/2013. So older drivers are worse, can not comment about the newer ones, so this part is take it or leave it.

Next will follow maximum possible upgrade, 7750 is weaker...

So far I found only 2 7770 video cards which will fit inside - PowerColor AX7770 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

HIS H777FN1G Radeon HD 7770 very tight fit, almost touching heatsink http://www.newegg.com/Product/Product.aspx?Item=N82E168...

7750 cards do not require power supply upgrade, 650 TI and 7770 are.

Unfortunately I bring you the bad news - not all cards can go inside Optiplex, and this is because Dell designed Optiplex for business not for home use. Inspiron in this case is much better in terms of upgrading.

I missed NVIDIA SPARKLE 700025 (SX650TI1024KD) GeForce GTX 650 Ti http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Sorry about the miss.

Would this addition prevent you from cutting brackets, I don't know how I forgot about 650 TI card.
